Description

Technical Field

[0001] The present invention relates to the technical field of retaining ring processing equipment, and particularly relates to a shearing device of a shearing machine. Background Art

[0002] During the processing of retaining rings, retaining rings with a certain opening are often formed by stamping on thin plates. In order to improve processing efficiency, processing is often carried out on continuous strip-shaped thin plates. In order to facilitate the treatment of waste materials, a shearing machine is used to shear the strip-shaped waste thin plates.

[0003] The shearing structure of the existing shearing machine often includes a lower shearing blade and an upper shearing blade. The material is between the upper shearing blade and the lower shearing blade. The upper shearing blade is moved downward to complete shearing. In order to improve the shearing efficiency and shearing effect, the side of the lower cutting edge of the upper shearing blade opposite to the cutting edge needs to be in the same vertical side plane. Since the upper shearing blade shears materials with a certain thickness and relatively high hardness, and the upper shearing blade and the lower shearing blade are often fixed to the tool holder or the frame by fasteners. If the fasteners become loose, the upper shearing blade or the lower shearing blade will be inclined to a certain extent. If the inclination degree with the cutting edge of the lower shearing blade is large, it will affect the shearing effect and efficiency of the material. Summary of the Invention

[0004] To solve the technical problems in the background art, the present invention proposes a shearing device of a shearing machine.

[0005] A shearing device of a shearing machine proposed by the present invention includes a frame, a lower shearing blade, an upper shearing blade, a lifting mechanism, an upper detection component and a lower detection component, wherein:

[0006] The lower shearing blade is installed on the frame, and the cutting edge of the lower shearing blade faces upward;

[0007] The upper shearing blade is installed on the frame through a lifting mechanism, and the cutting edge of the upper shearing blade faces downward. The cutting edge of the upper shearing blade is opposite to the cutting edge of the lower shearing blade. The side of the cutting edge of the upper shearing blade opposite to the lower shearing blade and the side of the cutting edge of the lower shearing blade opposite to the upper shearing blade are in the same vertical plane and form a shearing surface. It should be noted that the side of the cutting edge of the upper shearing blade opposite to the lower shearing blade is defined as the first cutting side surface, and the side of the cutting edge of the lower shearing blade opposite to the upper shearing blade is defined as the second cutting side surface. The shearing surface here is the same vertical plane where the first cutting side surface and the second cutting side surface are located before the upper shearing blade is deflected relative to the lower shearing blade; specifically, the lifting mechanism can be an electric cylinder or a cylinder or other mechanisms in the prior art that can drive components to reciprocate in the vertical direction;

[0008] The upper detection piece is installed at one end of the lower shearing knife, and the lower detection piece is installed on the lower shearing knife or the machine frame. The lower detection piece is opposite to the upper detection piece. During the process that the lifting mechanism drives the upper shearing knife to move vertically downward, the contact situation between the upper detection piece and the lower detection piece is used to judge whether the upper shearing knife is deflected relative to the lower shearing knife. Specifically, the upper detection piece has an upper contact part, and the lower detection piece has a standard part. When the upper detection piece is in contact with or opposite to the lower detection piece, it is judged whether the upper shearing knife is deflected relative to the lower shearing knife according to the relative position of the upper contact part and the standard part.

[0009] Specifically, it can be judged whether the upper shearing knife is inclined relative to the lower shearing knife by whether the distance between the side of the upper detection piece opposite to the lower detection piece changes.

[0010] As a further optimized solution of the present invention, the cutting edge of the lower shearing knife is in the horizontal direction, and the cutting edge of the upper shearing knife is an inclined plane that gradually slopes upward from the first side of the upper shearing knife to the second side of the upper shearing knife. The first side and the second side are opposite to each other. The upper detection piece is installed on one side of the upper shearing knife close to the second side, which is convenient for shearing and increases the detection accuracy.

[0011] In order to further increase the detection accuracy, as a further optimized solution of the present invention, the upper detection piece and the lower detection piece are in point contact or line contact.

[0012] In order to further increase the detection accuracy, as a further optimized solution of the present invention, when the upper shearing knife is not deflected, the contact point or contact position of the upper detection piece and the lower detection piece is located on the shearing surface.

[0013] As a further optimized solution of the present invention, the upper detection piece includes a contact ball and a connecting piece. The connecting piece is installed on the upper shearing knife, and the contact ball is installed on the connecting piece. If the part of the lower detection piece opposite to the upper detection piece is a point or a surface, it can ensure that the upper detection piece and the lower detection piece are in point contact.

[0014] As a further optimized solution of the present invention, the contact ball can rotate relative to the connecting piece along the center of the contact ball, reducing the friction between the contact ball and the lower detection piece, and thus ensuring the detection accuracy.

[0015] In order to further increase the detection accuracy, as a further optimized solution of the present invention, the lower detection member is a balance plate, which is horizontally rotatably installed on the lower shear knife. There are two groups of upper detection members, and the two groups of upper detection members are symmetric about the axis of rotation of the balance plate relative to the lower shear knife. If the upper shear knife and the lower shear knife are deflected, the contact time and position of the two spherical detection members with the balance plate are different, which causes the balance plate to deflect relative to the lower shear knife. By observing whether the balance plate is deflected, it can be determined whether the upper shear knife and the lower shear knife are deflected, which is convenient for more intuitively judging whether the upper shear knife and the lower shear knife are deflected.

[0016] As a further optimized solution of the present invention, a horizontal detector is provided in the middle of the balance plate, and the horizontal detector is symmetric about the axis of rotation of the balance plate relative to the lower shear knife, which is convenient for judging whether the balance plate is deflected.

[0017] As a further optimized solution of the present invention, it further includes a mounting block and an elastic member. The balance plate is horizontally rotatably installed on the mounting block, the mounting block is vertically slidably installed on the lower shear knife, and the elastic member is fixed between the mounting block and the lower shear knife. The elastic member can elastically deform in the vertical direction. When the lifting mechanism drives the lower shear knife to move downward, it ensures that the upper detection member can contact the lower detection member, thereby increasing the detection accuracy. Of course, the position of the mounting block can also be adjusted. After the upper shear knife is adjusted to move a certain position relative to the lower shear knife, the upper detection member contacts the lower detection member again. Specifically, the elastic member can be a spring or other components that can elastically deform.

[0018] As a further optimized solution of the present invention, it further includes a limit post and a limit sleeve. The limit sleeve is vertically fixed on the lower shear knife, the limit post is fixed on the mounting block, and the lower end of the limit post is vertically slidably installed on the limit sleeve to ensure the vertical movement of the mounting block and prevent it from deflecting, further increasing the detection accuracy.

[0019] In the present invention, the shearing device of the shearing machine proposed has a simple structure. During the process of the lifting mechanism driving the upper shear knife to move vertically downward, the contact situation between the upper detection member and the lower detection member is used to judge whether the upper shear knife is deflected relative to the lower shear knife. If the upper shear knife and the lower shear knife are deflected, it is convenient for the staff to take measures in time to make adjustments to ensure the shearing accuracy and increase the service life of the upper shear knife and the lower shear knife. If the upper shear knife and the lower shear knife are deflected only because the installation bolts or screws of the upper shear knife and the lower shear knife are loose, the upper shear knife and the lower shear knife can be aligned by tightening the screws. If the deflection of the upper shear knife and the lower shear knife is not caused by the loosening of the installation fasteners, the upper shear knife or the lower shear knife can be replaced according to the deflection situation to ensure the alignment of the upper shear knife and the lower shear knife.

[0020] Additional aspects and advantages of the present invention will be given in part in the following description, become apparent in part from the following description, or be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] As Figures 1-3 shown, a shearing device of a shearing machine includes a frame 1, a lower shearing blade 2, an upper shearing blade 3, a lifting mechanism 4, an upper detecting member 5, a lower detecting member 6, a horizontal detector 7, a mounting block 8 and an elastic member 9, wherein:

[0030] The lower shearing blade 2 is mounted on the frame 1 through a fastener, and the cutting edge of the lower shearing blade 2 faces upward, and the fastener is a fastening bolt;

[0031] The upper shearing blade 3 is mounted on the frame 1 through the lifting mechanism 4. Specifically, it includes a lifting frame. The upper shearing blade 3 is fixed on the lifting frame through a fastening bolt. The lifting frame is fixed at the lifting end of the lifting mechanism 4. The lifting mechanism 4 is an electric cylinder, and the cutting edge of the upper shearing blade 3 faces downward. The cutting edge of the upper shearing blade 3 is opposite to the cutting edge of the lower shearing blade 2. The side surface of the upper shearing blade 3 opposite to the lower shearing blade 2 and the side surface of the lower shearing blade 2 opposite to the upper shearing blade 3 are in the same vertical plane and form a shearing surface. It should be noted that the side surface of the upper shearing blade 3 opposite to the lower shearing blade 2 is defined as the first cutting side surface, and the side surface of the lower shearing blade 2 opposite to the upper shearing blade 3 is defined as the second cutting side surface. Here, the shearing surface is the same vertical plane where the first cutting side surface and the second cutting side surface are located before the upper shearing blade 3 is deflected relative to the lower shearing blade 2;

[0032] Specifically, the cutting edge of the lower shearing knife 2 is in the horizontal direction, and the cutting edge of the upper shearing knife 3 is an inclined plane that gradually slopes upward from the first side face close to the upper shearing knife 3 towards the second side face close to the upper shearing knife 3. The first side face and the second side face are opposite to each other. The upper detecting member 5 is installed on one side of the upper shearing knife 3 close to the second side face, and the first side face and the second side face are distributed on both sides of the upper shearing knife 3 along the length direction;

[0033] The upper detecting member 5 is installed at one end of the lower shearing knife 2 close to the second side face;

[0034] Specifically, the upper detecting member 5 includes a contact ball 50 and a connecting member 51. The connecting member 51 is detachably installed on the upper shearing knife 3 by screws. The contact ball 50 is installed on the connecting member 51. The center of the contact ball 50 is on the first cutting side face. If the part of the lower detecting member 6 opposite to the upper detecting member 5 is a point or a surface, it can ensure that the upper detecting member 5 and the lower detecting member 6 are in point contact;

[0035] Specifically, the contact ball 50 can rotate relative to the connecting member 51 around the center of the contact ball 50. Specifically, a spherical groove is opened at the lower end of the connecting member 51. The contact ball 50 is matched with the spherical groove and installed in the spherical groove. In order to reduce friction, there can be a solid lubricant, such as butter, in the spherical groove;

[0036] The lower detecting member 6 is installed on the lower shearing knife 2. The lower detecting member 6 is opposite to the upper detecting member 5, and when the lower detecting member 6 contacts the upper detecting member 5, it is in point contact;

[0037] The lower detecting member 6 is a balance plate, and the balance plate is horizontally rotatably installed on the lower shearing knife 2;

[0038] The balance plate is horizontally rotatably installed on the mounting block 8. The balance plate is parallel to the lower shearing knife 2. The width of the top surface of the balance plate opposite to the upper detecting member 5 is very narrow and almost a line. The topmost part of the balance plate is defined as the balance line, and the balance line is located within the second cutting side face;

[0039] The mounting block 8 is vertically slidably installed on the lower shearing knife 2, and the elastic member 9 is fixed between the mounting block 8 and the lower shearing knife 2. The elastic member 9 can elastically deform in the vertical direction. When the lifting mechanism 4 drives the lower shearing knife 2 to move downward, it ensures that the upper detecting member 5 can contact the lower detecting member 6, thereby increasing the detection accuracy. Of course, the position of the mounting block 8 can also be adjusted. After adjusting the position of the upper shearing knife 3 relative to the lower shearing knife 2 by a certain position, the upper detecting member 5 contacts the lower detecting member 6 again. Specifically, the elastic member 9 is a spring;

[0040] It also includes a limit post 11 and a limit sleeve 10. The limit sleeve 10 is vertically fixed on the lower shearing knife 2, the limit post 11 is fixed on the mounting block 8, and the lower end of the limit post 11 is vertically slidably installed on the limit sleeve 10. A spring is sleeved outside the limit post 11, and both ends of the spring are fixed on the limit sleeve 10 and the mounting block 8, ensuring the vertical movement of the mounting block 8 and avoiding its skew to further increase the detection accuracy;

[0041] There are two groups of upper detection parts 5, and the two groups of upper detection parts 5 are symmetric about the axis of rotation of the balance plate relative to the lower shearing knife 2. If the upper shearing knife 3 and the lower shearing knife 2 are skewed, the contact time and position of the two spherical detection parts with the balance plate are different, which will cause the balance plate to rotate and skew relative to the lower shearing knife 2. By observing whether the balance plate is skewed, it can be determined whether the upper shearing knife 3 and the lower shearing knife 2 are skewed, which is convenient for more intuitively judging whether the upper shearing knife 3 and the lower shearing knife 2 are skewed;

[0042] The level detector 7 is installed on the flat plate, and the level detector 7 is symmetric about the axis of rotation of the balance plate relative to the lower shearing knife 2, which is convenient for more intuitively judging whether the balance plate is skewed.

[0043] During the working process, if the upper shearing knife 3 and the lower shearing knife 2 are not skewed, when the lifting mechanism 4 drives the upper shearing knife 3 to move vertically downward, when the upper shearing knife 3 moves to a certain position, the two contact balls 50 simultaneously contact the balance line of the balance plate, and the balance plate will not be skewed. When the lifting mechanism 4 continues to move downward to compress the elastic part 9, since the upper shearing knife 3 and the lower shearing knife 2 are not loose, the balance plate is ensured to be horizontal, and the level detector 7 shows balance. If the locking parts of the upper shearing knife 3 or the lower shearing knife 2 are loose, due to the action of the elastic part 9 and the contact balls 50, the balance plate will be skewed, which can be directly observed through the level detector 7, facilitating the staff to take measures in time for adjustment to ensure the shearing accuracy and increase the service life of the upper shearing knife 3 and the lower shearing knife 2. If the upper shearing knife 3 and the lower shearing knife 2 are skewed only because the installation bolts or screws of the upper shearing knife 3 and the lower shearing knife 2 are loose, the upper shearing knife 3 and the lower shearing knife 2 can be aligned by tightening the screws. If the skew of the upper shearing knife 3 and the lower shearing knife 2 is not caused by the looseness of the installation fasteners, the upper shearing knife 3 or the lower shearing knife 2 can be replaced according to the skew situation to ensure the alignment of the upper shearing knife 3 and the lower shearing knife 2.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
